Inconsistent naming triggered for no apparent reason.

Our team uses the naming rule UpperCamelCase_UnderscorTolerant for our C# project.

I have the following method:

    private string FrameNumberToString(int frameNumber)
    {

        <stuff>

    }

For some reason, I get a warning that the name is inconsistent and it suggest I rename the method to NumberToString. This happens with variables to; any mention of "Frame" is met with extreme prejudice.

It is possible that because we share the same dotsettings with the team that somebody has introduced some interesting setting - perhaps even myself by mistake - but I can't even think why there should be a prejudice against Frames.

Even FameNumberToString is acceptable for some reason while FrameNumberToString is not.

As there is a lot of mentions of Frames in this project, this is getting very annoying.
